ATTACHMENT FOR LISTEB-GULTIVATQES. r

Specification of Letters Patent.

Patented Jan. l5, rare.

V Application filed August 20,1917. Serial No. 187,183.

To all whom it may concern:

I Be it known that 1, WILLIAM F. Bnsomrn, a citizen of theUnitcdifcltates, residing at Wichita, in the county" of Sedgwick andState of Kansas, have invented certain new and useful improvements inAttachments for Lister-Cultivators; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention has for its principal object to provide a simplyconstructed and incripensive arrangement of parts whereby any of thewell known types of lister Cultivators,

may be easily'converted for use as ridge busters, that is for thepurpose of cultivating the ridges as well as the furrows. Another objectof the invention is to so mount the cultivator disks asto permit them tobe easily adjusted by a hand lever or the like, so that they may be madeto draw a greater or less amount of earth from the ridges.

Yet another object is to so construct the adjusting means of the disks,as to permit said means to be easily secured to and operated by thetransverserock shaft which is usually employed for raising and loweringthe shovels.

With the foregoing general objects in view, the invention resides in thenovel features of construction andu'nique combinations of parts to behereinafter fully described and claimed, the descriptivematter beingsupplemented by the accompanying" drawings which form a part of thisspecification and in which Figure 1 is a top plan view showing one ofthe improved attachments applied to a portion of a lister cultivator;

Fig. 2 is a rear elevation of Fig. 1; and

Fig. 3 is a longitudinal section on substantially the plane indicated bythe line 3-3 of Fig. 1.

In the drawings above brieflydcscribed, the numeral 1 designates aportion of the connecting bar which usually extends between the twohalves or units of lister cultivators which are constructed foroperating By means of the arm 2 or any other suitable device, thebracket 3 on the rear end of the tongue 4, is swiveled to the bar 1, atransverse tubular frame member 5 being hinged at 6 to the bracket 3 forvertical swinging, said frame member carrying the usual standards 7 uponwhose lower ends the furrow wheels 8 are rotatably mounted. Passingthrough the tubular frame member 5, is a rock shaft 9 having squaredends, it beingupon said ends that the shovels are usually mounted.Wl'icn applying the presentinvention, however, these shovels areomitted, but the adjusting lever-l0 ofthe shaft 9 and the rack 11thereof, are retained since other parts are operated from the shaft 9and the latter must therefore be held in adjusted position. i

c The construction so farbriefiy described may be found in a number ofwell known types of lister cultivator-s which operate 'upon the bellcrank principle, that is by swinging the wheels 8 upwardly anddownwardly to respectively lower or raise the cultivator disks. In thepresent showing, this swinging of the wheels 8 is accomplished'by meansof a lever 12 which is fulcrumed to the tongue at and connected by meansof suitable links or the like 13with the axles of the wheels 8. It is tobe understood that this adjustment constitutes no part of the presentinvention but that it, as well as the features above described, areshown only for the purpose of illustrating the application of theimproved features.

The usual disk carrying means are detached fram the frame member 5 andan inclined hanger or arm 14 is secured thereto between the standards 7the upper end of said arm having a right angular seat 15 which receivesthe similarly shaped frame member 5, pivot-ally connected bolts 16 beingprovided for passage around the remainder of the member 5 for thepurpose of securing it rigidly in the seat. The lower end of the arm 14is preferably widened and provided with a pair of toothed bosses 17 withwhich similarly toothed plates 18 on a pair of vertically disposedbearings 19 coact, bolts or the like 20 being provided for securing saidplates to the bosses, so that the bearings 20 may be adjusted from thevertical, whenever occasion should demand.

Pivotally connected with the lower or rear end of the arm ll, by meansof vertical studs 21 which are received in the bearings 20, are twohorizontally swinging shafts 22, said shafts carrying the usual or anypreferred type of cultivator disks 23 which are mounted rotatablythereon. At 24-, a pair of links 25 are pivoted to the shafts 22, thefront ends of said links being similarly connected with crank arms 26,said arms having guides 27 and set screws 28 for seof said wheels'andhaving a pair of sub curing them on the squared ends-of'thestant1allyvertical bearings, a pair of transshaft 9, so that turningofrsaidvshaft,.by means of the lever 10, will swing the shafts 22 forwardly andrearwardlyto vary the angular relation of the disks 23, whereuponthelatter are caused to move a greater orless amount of earth. In mosttypes of the invention, one of the crank arms 26, in ad .dition to theguides 27 and screws 28, will be equipped with a channel shaped arm 29by means of which the lever 10 is attached thereto. In other cases,however, in which the lever is" permanently secured to the shaft '9 itisunnecessary to provide the arm 29. By constructing the attachment as orsubstantially as above described, it may be eas- 11y and inexpensivelymanufactured and marketed, yet will be attachable to practically alltypes of lister cultivators, thus making it possible to convert thecomparatively light cultivators into substantial ridge busters. Onemachine. may thusbe used for the two purposes, so that expense isgreatly decreased. On account of these advantages, the specific featuresof construction shown and described, constitute the preferred form ofthe attachment. I wish it understood, however, that within the scope ofthe invention as claimed, numerous minor changes may well be made.

"I claim:

'1. In a lister cultivator, the combination of a transverse rockableframe member and means for rocking it, a pair of spaced standardsdepending rigidly from said frame member and wheels on the lower ends ofsaid standards, a single inclined arm secured rigidly at its upper endto said frame member between said standards, the lower end of said armbeing disposed centrally in rear .verse disk-carrying shafts pivoted attheir inner ends to said bearings for horizontal sw1nging,l1nksextending forwardly from said shafts, crank arms to which said links areconnected, a transverse rock shaft adjacent said framemember andcarrying sald crank' arms, and means for rocking said shaft. p j

2. An attachment for lister cultivators comprising an inclined arinwidened-hori- 'zontally at its apper 'a. 1 0we1- ends. and having atsaidupperlend a. transversely extending L-sliaped seatyto receive atransverse frame member of the cultivatonmeans coacting with sa d seatfor, r gidly securing said arm to saidframe.member, the lower end ofsaid arm being disposed in a vertica l transverse plane and havinghorizontally spaced bosses whose rear s1des are toothed,

pairof platesfhaving' teeth engaging the teeth of said bosses,bolts.connecting said plates and bosses to permit turning of the former,substantially vertical bearings formed on the outer edge portions orsaid plates, 'a pair of transverse 'disk carrying shaftswhose inner endsarepivoted to said bearings for horizontal swinging, and links extendingforwardly from said shafts and having crank arms at their front ends formounting. on a transverse rock shaft" of the cultivator. 1
